A second string Sydney FC side bearing no resemblance to their A-League grand final winning team have lost 4-0 at home to Japan's Kawasaki Frontale, in their last AFC Champions League group game.
The Sky Blues, who had no chance of making the knockout stage, didn't field any of the side that started Sunday's domestic season decider against Perth Glory at Optus Stadium
Their run-on team for Tuesday's game at Sydney's Jubilee Oval, included Iranian international Reza Ghoochannejhad, who scored the clinching penalty on Sunday, and Anthony Caceres, who also came off the bench in Perth.
Before the game, the starting members of Sunday's team took turns to hold aloft the trophy before a crowd of 3813, Sydney's lowest-ever Champions League home attendance.
Adding to the bizarre atmosphere, the sponsor's name on the trophy needed to have some tape stuck over it, as it was a rival of one of the competition's backers.
Sydney finished bottom of their group with three points, all from draws and it was their heaviest ever Champions League defeat.
A youthful side, that included two debutants, was overwhelmed by a team including Brazilian international Leandro Damiao.
Kawasaki scored three times in the first half hour and had 23 attempts to Sydney's five in front of the small but loud crowd, with both sets of supporters in good voice.
The visitors had numerous other chances either saved by former Central Coast Mariners goalkeeper Thomas Heward-Belle, or were off target.
Ghoochannejhad came closest to scoring for Sydney with a 52nd minute chip which hit the bar, with Luke Ivanovic blazing a follow-up shot over.
Two quality finishes from Yasuto Wakizaka in the ninth and 20th minutes put the visitors in control and they added a third through Ao Tanaka, whose shot deflected off Sydney debutant Patrick Scibilio.
Damiao got the fourth just before the hour, dispossessing Cam Devlin and charging forward before unleashing an unstoppable shot from the edge of the area.
It took Sydney 39 minutes to fashion a good scoring opportunity.
Devlin had a close range backheel blocked by goalkeeper Jung Sunryong, who saved a Jacob Tratt header from the following corner.
Sydney have never beaten a Japanese team in ten games in the competition.
